Door Locks
Your vehicle may be equipped with an automatic
lock/unlock feature which enables you to program your
vehicle’s power door locks. You can program this
feature through the Driver Information Center (DIC), or
by the following method. SeeDIC Vehicle Customization
on page 3-63.
Programmable Locking Feature
Following are the two available programming options:
Mode 1:All doors lock when the transmission is shifted
into gear. This is the mode that is pre-programmed in
the factory for your vehicle for automatic transmission
vehicles.
Mode 2:All doors lock when the vehicle speed is
greater than 8 mph (13 km/h). This is the mode that is
pre-programmed in the factory for manual transmission
vehicles.
The following instructions tell you how to change the
automatic door lock mode (automatic transmission only).
Choose one of the two programming options listed
above before entering the program mode.To enter the program mode, do the following:
1. Begin with the ignition off. Then pull the turn
signal/multifunction lever toward you and hold
it there while you perform the next step.
2. Turn the key to RUN then back to LOCK twice.
Then, with the key in LOCK, release the turn
signal/multifunction lever. Once you do this, the
doors will lock and unlock, the horn will chirp twice,
and a 30-second timer will begin. You are now
ready to program the automatic door lock feature.
3. Press the door lock switch once. You will hear either
one or two chimes. The number of chimes tells you
which lock mode is currently selected. Continue
to press the door lock switch until the number
of chimes that you hear matches the number of the
mode that you want. If you take longer than
30 seconds, the locks will automatically lock and
unlock and the horn will chirp twice to indicate that
you have left the program mode. If this occurs,
you can repeat the procedure beginning with Step 1
to re-enter the programming mode.
You can exit the program mode any time by turning the
ignition to RUN (the doors will automatically lock and
unlock and the horn will chirp twice to indicate that you
are leaving the program mode). If the lock/unlock
switches are not pressed while in the programming mode,
the current automatic settings will not be modied.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle may be equipped with a content
theft-deterrent alarm system.
The security light, located
on the instrument panel
cluster, will ash as
you open the door, while
the ignition is off, to
indicate the system is
being activated.This message reminds you to activate the theft-deterrent
system. Here is how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The security
light should come on and ash. If using the
remote keyless entry transmitter, the door does not
need to be open.
If the delayed locking feature is active, the alarm
will not be activated until all doors are closed
and the security light goes off.
3. Close all doors. The security light will stop ashing
and go off after approximately 30 seconds.
The content theft deterrent alarm is not armed until
the security light goes off.
If a door is opened without using the remote keyless
entry transmitter, the alarm will go off. Your vehicle’s
headlamps will ash and the horn will sound for
about two minutes, then will turn off to save the
battery power.
2-19

The theft-deterrent system will not activate if you lock
the doors with a key or use the manual door lock.
It activates only if you use a power door lock switch
with the door open, or with the remote keyless
entry transmitter. You should also remember that you
can start your vehicle with the correct ignition key if the
alarm has been set off.
Here is how to avoid setting off the alarm by accident:
If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the
door key after the doors are closed.
Always unlock a door with the remote keyless entry
transmitter. Unlocking a door any other way will set
off the alarm if the system has been armed.
If you set off the alarm by accident, you can turn off the
alarm by pressing unlock on the remote keyless
entry transmitter. You can also turn off the alarm by
placing the key in the ignition and turning it to START.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s window
and open the driver’s door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for
the security light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door.
This should set off the alarm.
If the alarm does not sound when it should, but the
vehicle’s headlamps ash, check to see if the horn
works. The horn fuse may be blown. To replace the
fuse, seeFuses and Circuit Breakers on page 5-123.
If the alarm does not sound or the vehicle’s headlamps
do not ash, see your dealer for service.

Passlock®
Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock
®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder is
turned with a valid key. If a correct key is not used or the
ignition lock cylinder is tampered with, fuel is disabled.
If the engine stalls and the security light ashes,
wait until the light stops ashing before trying to restart
the engine. Remember to release the key from
START as soon as the engine starts.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the
engine off. However, your Passlock
®system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
®at
this time. You may also want to check the fuse.
SeeFuses and Circuit Breakers on page 5-123.
See your dealer for service.
In an emergency, call the GM Roadside Assistance
Center. SeeRoadside Assistance Program on page 7-6.
Starting and Operating
Your Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Keep your speed at 55 mph (88 km/h) or less for
the rst 500 miles (805 km).
Do not drive at any one speed, fast or slow,
for the rst 500 miles (805 km). Do not make
full-throttle starts.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new brake
linings are not yet broken in. Hard stops with new
linings can mean premature wear and earlier
replacement. Follow this breaking-in guideline
every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing a
Trailer on page 4-69for more information.
2-21

Ignition Positions
With the key in the ignition switch, you can turn it to
four different positions.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in.
If it is, turn the steering wheel left and right while
you turn the key hard. If none of this works,
then your vehicle needs service.A (Lock):This position locks your ignition when the key
is removed. The steering locks when equipped with a
manual transmission. It is a theft-deterrent feature.
You will only be able to remove your key when
the ignition is turned to LOCK
B (Accessory):This position allows you to use things
like the radio, power windows and the windshield
wipers when the engine is off.
{CAUTION:
On manual transmission vehicles, turning the
key to LOCK will lock the steering column and
result in a loss of ability to steer the vehicle.
This could cause a collision. If you need to
turn the engine off while the vehicle is moving,
turn the key only to ACCESSORY. Do not
press the key release button while the vehicle
is moving.
C (Run):This is the position for driving.
D (Start):This position starts your engine.
2-22

Key Release Button

removed from the ignition
of manual transmission
vehicles unless the key
release button is used.

This feature assists in starting the engine and protects
the electrical system. This feature may cause the
engine to crank even after the ignition key is not in
START.
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only. If you have a diesel
engine refer to the diesel supplement for the starting
procedure.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
